01 - Pat the shrimp completely dry with paper towels. Season thoroughly with salt and black pepper, ensuring even coverage.
02 - Arrange three shallow bowls: place cornstarch in the first, beaten eggs in the second, and panko breadcrumbs in the third. Line a baking sheet with parchment paper for breaded shrimp.
03 - Dredge each shrimp in cornstarch, shaking off excess. Dip into egg mixture, allowing excess to drip off. Press firmly into panko breadcrumbs to coat completely. Transfer to prepared baking sheet.
04 - In a medium bowl, whisk together mayonnaise, sweet chili sauce, Sriracha, honey or sugar, and rice vinegar until smooth and well combined. Set aside for serving.
05 - Pour 2 inches of vegetable oil into a deep skillet or heavy-bottomed pot. Heat to 350°F, maintaining temperature throughout frying.
06 - Fry breaded shrimp in small batches for 2–3 minutes until golden brown and cooked through. Use a slotted spoon to transfer to paper towel-lined plate to drain excess oil.
07 - Transfer fried shrimp to a large bowl. Pour Bang Bang sauce over shrimp and toss gently until evenly coated.
08 - Arrange coated shrimp on a serving platter. Sprinkle with sliced green onions and toasted sesame seeds. Serve immediately while crispy.
